HENRY CALVIN WIN EBRENNER, OF BALTIMORE, MARYLAND, ASSIGNOR TO THE SCOTTMANUFACTURING COMPANY OF BALTIMORE CITY.

STEAM-CRANE.

SPECIFICATION forming part of Letters Patent No. 337,724, dated March 9,1886.

(No model.)

To all whom it may concern:

Be it known that I, HENRY CALVIN WINE- BRENNER, of the city of Baltimoreand State of Maryland, have invented certain Improvements in Steam-Cranes, of which the following is a specification.

This invention relates to the combination, with crane, of a steam-enginewith its steam and exhaust pipes situated in a line corresponding withthe axis of the post, whereby the crane may be turned in any directionwithout affecting the admission to and exhaust of steam from the engine.

It further relates to details of construction of certain parts of thecrane, as will hereinafter fully appear.

The drawing forming apart hereof is aside elevation, partly in section,of a crane embodying my improvements.

A is the post of the crane, having at its lower end the gudgeon a, whichrests in a step, b. The upper end of the post is supported by means of apipe, 0, which passes through and is adapted to turn freely in collarsd, secured to a frame, B, which may be a portion of an upper floor. Thepipe 0 is connected to the post A by means of a collar, e, having legsflet in and bolted to the post A. The upper end of the pipe 0 enters astationary chamber, C, through a stuffing-box, g, and is supported by aflange, h, which rests on a ring, t", sup ported by set-screws, asshown. This pipe 0 forms a part of the steam-pipe, and is attached atits lower end to a second chamber, D.

E represents the engine, which is of the rotary type and needs nodescription herein, as it forms no part of my present invention.

The steam-pipe j, which leads from the boiler, (not show 11,) enters thechamber C, and a second steam-pipe, which connects directly with theengine, is denoted by k.

The exhaust-pipe Z from the engine passes entirely through the chamberD, the pipe 0, and the other chamber, C. and may extend above thechamber to any desired height.

The chambers C and D are provided with stuffing-boxes, to prevent escapeof steam, and the exl1aust-pipe Z.

It will be seen that in the swinging motion of the crane the pipes whichmove with it maintain under all circumstances an axial position, and theflow of steam is therefore not interfered with.

I claim as my invention- 1. In combination with a crane, a steamenginewith a portionof its steam and exhaust pipes placed in a linecorresponding with the axial line of the crane-post, whereby the flow ofsteam to and from the engine is not interfered with in the swinging ofthe crane, substantially as specified.

2. In combination with the swinging post of a crane,asteam-chambersituated above the post and on the axial line thereof,centrallyplaced steam and exhaust pipes, and a steamengine,substantially as specified.

3. In combination with the swinging cranepost A, the chambers C and D,connecting pipe 0, steam-pipesj and 7c, and exhaust-pipe l,substantially as specified.
